I don't think your mother (or anyone else obviously) knew what was going on or can really understand now. Were I you, I'd join with other Straight survivors
http://www.geocities.com/surviving_s..._inc/index.htm and see what comfort, understanding, help you can get from them. Reading the horrific stories on the Net, I don't think it is something that your mother would want to face/believe so I don't think confronting her at this time would get you the result you long for. I would find a good therapist and work on it all from there.
